I'm using phpThumb - the PHP thumbnail generator.
'phpThumb.config.php':
$PHPTHUMB_CONFIG['cache_maxage'] = 10;
$PHPTHUMB_CONFIG['cache_maxsize'] = 1000;
$PHPTHUMB_CONFIG['cache_maxfiles'] = 10;
but it does nothing... I've got 108 MB in 922 files... and it keeps growing.
Thanks for any suggestions.
